Nursing: How to Write a Literature Review

  • Traditional or Narrative Literature Review

Getting started

1. start with your research question, 2. search the literature, 3. read & evaluate, 4. finalize results, 5. write & revise, brainfuse online tutoring and writing review.

  • RESEARCH HELP

The best way to approach your literature review is to break it down into steps.  Remember, research is an iterative process, not a linear one.  You will revisit steps and revise along the way.  Get started with the handout, information, and tips from various university Writing Centers below that provides an excellent overview.  Then move on to the specific steps recommended on this page.

  • UNC- Chapel Hill Writing Center Literature Review Handout, from the University of North Carolina at Chapel Hill.
  • University of Wisconsin-Madison Writing Center Learn how to write a review of literature, from the University of Wisconsin-Madison.
  • University of Toronto-- Writing Advice The Literature Review: A few tips on conducting it, from the University of Toronto.
  • Begin with a topic.
  • Understand the topic. 
  • Familiarize yourself with the terminology.  Note what words are being used and keep track of these for use as database search keywords. 
  • See what research has been done on this topic before you commit to the topic.  Review articles can be helpful to understand what research has been done .
  • Develop your research question.  (see handout below)
  • How comprehensive should it be? 
  • Is it for a course assignment or a dissertation? 
  • How many years should it cover?
  • Developing a good nursing research question Handout. Reviews PICO method and provides search tips.

Your next step is to construct a search strategy and then locate & retrieve articles.

  •  There are often 2-4 key concepts in a research question.
  • Search for primary sources (original research articles.)
  • These are based on the key concepts in your research question.
  • Remember to consider synonyms and related terms.
  • Which databases to search?
  • What limiters should be applied (peer-reviewed, publication date, geographic location, etc.)?

Review articles (secondary sources)

Use to identify literature on your topic, the way you would use a bibliography.  Then locate and retrieve the original studies discussed in the review article. Review articles are considered secondary sources.

  • Once you have some relevant articles, review reference lists to see if there are any useful articles.
  • Which articles were written later and have cited some of your useful articles?  Are these, in turn, articles that will be useful to you? 
  • Keep track of what terms you used and what databases you searched. 
  • Use database tools such as save search history in EBSCO to help.
  • Keep track of the citations for the articles you will be using in your literature review. 
  • Use RefWorks or another method of tracking this information. 
  • Database Search Strategy Worksheet Handout. How to construct a search.
  • TUTORIAL: How to do a search based on your research question This is a self-paced, interactive tutorial that reviews how to construct and perform a database search in CINAHL.

The next step is to read, review, and understand the articles.

  • Start by reviewing abstracts. 
  • Make sure you are selecting primary sources (original research articles).
  • Note any keywords authors report using when searching for prior studies.
  • You will need to evaluate and critique them and write a synthesis related to your research question.
  • Consider using a matrix to organize and compare and contrast the articles . 
  • Which authors are conducting research in this area?  Search by author.  
  • Are there certain authors’ whose work is cited in many of your articles?  Did they write an early, seminal article that is often cited?
  • Searching is a cyclical process where you will run searches, review results, modify searches, run again, review again, etc. 
  • Critique articles.  Keep or exclude based on whether they are relevant to your research question.
  • When you have done a thorough search using several databases plus Google Scholar, using appropriate keywords or subject terms, plus author’s names, and you begin to find the same articles over and over.
  • Remember to consider the scope of your project and the length of your paper.  A dissertation will have a more exhaustive literature review than an 8 page paper, for example.
  • What are common findings among each group or where do they disagree? 
  • Identify common themes. Identify controversial or problematic areas in the research. 
  • Use your matrix to organize this.
  • Once you have read and re-read your articles and organized your findings, you are ready to begin the process of writing the literature review.

2. Synthesize.  (see handout below)

  • Include a synthesis of the articles you have chosen for your literature review.
  • A literature review is NOT a list or a summary of what has been written on a particular topic. 
  • It analyzes the articles in terms of how they relate to your research question. 
  • While reading, look for similarities and differences (compare and contrast) among the articles.  You will create your synthesis from this.
  • Synthesis Examples Handout. Sample excerpts that illustrate synthesis.

Good Place to Start: Citation Databases

Interdisciplinary Citation Databases:

A good place to start your research  is to search a research citation database to view the scope of literature available on your topic.

TIP #1: SEED ARTICLE Begin your research with a "seed article" - an article that strongly supports your research topic.  Then use a citation database to follow the studies published by finding articles which have cited that article, either because they support it or because they disagree with it.

TIP #2: SNOWBALLING Snowballing is the process where researchers will begin with a select number of articles they have identified relevant/strongly supports their topic and then search each articles' references reviewing the studies cited to determine if they are relevant to your research.

BONUS POINTS: This process also helps identify key highly cited authors within a topic to help establish the "experts" in the field.

Begin by constructing a focused research question to help you then convert it into an effective search strategy.

  • Identify keywords or synonyms
  • Type of study/resources
  • Which database(s) to search
  • Asking a Good Question (PICO)
  • PICO - AHRQ
  • PICO - Worksheet
  • What Is a PICOT Question?

Seminal Works: Search Key Indexing/Citation Databases

  • Google Scholar
  • Web of Science

TIP – How to Locate Seminal Works

  • DO NOT: Limit by date range or you might overlook the seminal works
  • DO: Look at highly cited references (Seminal articles are frequently referred to “cited” in the research)
  • DO: Search citation databases like Scopus, Web of Science and Google Scholar

What is a literature review?

A literature review is a comprehensive and up-to-date overview of published information on a subject area. Conducting a literature review demands a careful examination of a body of literature that has been published that helps answer your research question (See PICO). Literature reviewed includes scholarly journals, scholarly books, authoritative databases, primary sources and grey literature.

A literature review attempts to answer the following:

  • What is known about the subject?
  • What is the chronology of knowledge about my subject?
  • Are there any gaps in the literature?
  • Is there a consensus/debate on issues?
  • Create a clear research question/statement
  • Define the scope of the review include limitations (i.e. gender, age, location, nationality...)
  • Search existing literature including classic works on your topic and grey literature
  • Evaluate results and the evidence (Avoid discounting information that contradicts your research)
  • Track and organize references
  • How to conduct an effective literature search.
  • Social Work Literature Review Guidelines (OWL Purdue Online Writing Lab)

What is PICO?

The PICO model can help you formulate a good clinical question. Sometimes it's referred to as PICO-T, containing an optional 5th factor.

Systematic Literature Reviews: Steps & Resources

literature review nursing examples

These steps for conducting a systematic literature review are listed below . 

Also see subpages for more information about:

  • The different types of literature reviews, including systematic reviews and other evidence synthesis methods
  • Tools & Tutorials

Literature Review & Systematic Review Steps

  • Develop a Focused Question
  • Scope the Literature  (Initial Search)
  • Refine & Expand the Search
  • Limit the Results
  • Download Citations
  • Abstract & Analyze
  • Create Flow Diagram
  • Synthesize & Report Results

1. Develop a Focused   Question 

Consider the PICO Format: Population/Problem, Intervention, Comparison, Outcome

Focus on defining the Population or Problem and Intervention (don't narrow by Comparison or Outcome just yet!)

"What are the effects of the Pilates method for patients with low back pain?"

Tools & Additional Resources:

  • PICO Question Help
  • Stillwell, Susan B., DNP, RN, CNE; Fineout-Overholt, Ellen, PhD, RN, FNAP, FAAN; Melnyk, Bernadette Mazurek, PhD, RN, CPNP/PMHNP, FNAP, FAAN; Williamson, Kathleen M., PhD, RN Evidence-Based Practice, Step by Step: Asking the Clinical Question, AJN The American Journal of Nursing : March 2010 - Volume 110 - Issue 3 - p 58-61 doi: 10.1097/01.NAJ.0000368959.11129.79

2. Scope the Literature

A "scoping search" investigates the breadth and/or depth of the initial question or may identify a gap in the literature. 

Eligible studies may be located by searching in:

  • Background sources (books, point-of-care tools)
  • Article databases
  • Trial registries
  • Grey literature
  • Cited references
  • Reference lists

When searching, if possible, translate terms to controlled vocabulary of the database. Use text word searching when necessary.

Use Boolean operators to connect search terms:

  • Combine separate concepts with AND  (resulting in a narrower search)
  • Connecting synonyms with OR  (resulting in an expanded search)

Search:  pilates AND ("low back pain"  OR  backache )

Video Tutorials - Translating PICO Questions into Search Queries

  • Translate Your PICO Into a Search in PubMed (YouTube, Carrie Price, 5:11) 
  • Translate Your PICO Into a Search in CINAHL (YouTube, Carrie Price, 4:56)

3. Refine & Expand Your Search

Expand your search strategy with synonymous search terms harvested from:

  • database thesauri
  • reference lists
  • relevant studies

Example: 

(pilates OR exercise movement techniques) AND ("low back pain" OR backache* OR sciatica OR lumbago OR spondylosis)

As you develop a final, reproducible strategy for each database, save your strategies in a:

  • a personal database account (e.g., MyNCBI for PubMed)
  • Log in with your NYU credentials
  • Open and "Make a Copy" to create your own tracker for your literature search strategies

4. Limit Your Results

Use database filters to limit your results based on your defined inclusion/exclusion criteria.  In addition to relying on the databases' categorical filters, you may also need to manually screen results.  

  • Limit to Article type, e.g.,:  "randomized controlled trial" OR multicenter study
  • Limit by publication years, age groups, language, etc.

NOTE: Many databases allow you to filter to "Full Text Only".  This filter is  not recommended . It excludes articles if their full text is not available in that particular database (CINAHL, PubMed, etc), but if the article is relevant, it is important that you are able to read its title and abstract, regardless of 'full text' status. The full text is likely to be accessible through another source (a different database, or Interlibrary Loan).  

  • Filters in PubMed
  • CINAHL Advanced Searching Tutorial

5. Download Citations

Selected citations and/or entire sets of search results can be downloaded from the database into a citation management tool. If you are conducting a systematic review that will require reporting according to PRISMA standards, a citation manager can help you keep track of the number of articles that came from each database, as well as the number of duplicate records.

In Zotero, you can create a Collection for the combined results set, and sub-collections for the results from each database you search.  You can then use Zotero's 'Duplicate Items" function to find and merge duplicate records.

  • Citation Managers - General Guide

6. Abstract and Analyze

  • Migrate citations to data collection/extraction tool
  • Screen Title/Abstracts for inclusion/exclusion
  • Screen and appraise full text for relevance, methods, 
  • Resolve disagreements by consensus

Covidence is a web-based tool that enables you to work with a team to screen titles/abstracts and full text for inclusion in your review, as well as extract data from the included studies.

  • Data Extraction Tools

7. Create Flow Diagram

The PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) flow diagram is a visual representation of the flow of records through different phases of a systematic review.  It depicts the number of records identified, included and excluded.  It is best used in conjunction with the PRISMA checklist .

Example PRISMA diagram showing number of records identified, duplicates removed, and records excluded.

Multi-level diabetes prevention and treatment interventions for Native people in the USA and Canada: A scoping review. Current Diabetes Reports, 2 (11), 46. https://doi.org/10.1007/s11892-021-01414-3

  • PRISMA Flow Diagram Generator (ShinyApp.io, Haddaway et al. )
  • PRISMA Diagram Templates  (Word and PDF)
  • Make a copy of the file to fill out the template
  • Image can be downloaded as PDF, PNG, JPG, or SVG
  • Covidence generates a PRISMA diagram that is automatically updated as records move through the review phases

8. Synthesize & Report Results

There are a number of reporting guideline available to guide the synthesis and reporting of results in systematic literature reviews.

It is common to organize findings in a matrix, also known as a Table of Evidence (ToE).

Example of a review matrix, using Microsoft Excel, showing the results of a systematic literature review.

Literature Review Overview

What is a Literature Review? Why Are They Important?

A literature review is important because it presents the "state of the science" or accumulated knowledge on a specific topic. It summarizes, analyzes, and compares the available research, reporting study strengths and weaknesses, results, gaps in the research, conclusions, and authors’ interpretations.

Tips and techniques for conducting a literature review are described more fully in the subsequent boxes:

  • Literature review steps
  • Strategies for organizing the information for your review
  • Literature reviews sections
  • In-depth resources to assist in writing a literature review
  • Templates to start your review

Literature Review Steps

literature review nursing examples

Graphic used with permission: Torres, E. Librarian, Hawai'i Pacific University

1. Choose a topic and define your research question

  • Try to choose a topic of interest. You will be working with this subject for several weeks to months.
  • Ideas for topics can be found by scanning medical news sources (e.g MedPage Today), journals / magazines, work experiences, interesting patient cases, or family or personal health issues.
  • Do a bit of background reading on topic ideas to familiarize yourself with terminology and issues. Note the words and terms that are used.
  • Develop a focused research question using PICO(T) or other framework (FINER, SPICE, etc - there are many options) to help guide you.
  • Run a few sample database searches to make sure your research question is not too broad or too narrow.
  • If possible, discuss your topic with your professor. 

2. Determine the scope of your review

The scope of your review will be determined by your professor during your program. Check your assignment requirements for parameters for the Literature Review.

  • How many studies will you need to include?
  • How many years should it cover? (usually 5-7 depending on the professor)
  • For the nurses, are you required to limit to nursing literature?

3. Develop a search plan

  • Determine which databases to search. This will depend on your topic. If you are not sure, check your program specific library website (Physician Asst / Nursing / Health Services Admin) for recommendations.
  • Create an initial search string using the main concepts from your research (PICO, etc) question. Include synonyms and related words connected by Boolean operators
  • Contact your librarian for assistance, if needed.

4. Conduct searches and find relevant literature

  • Keep notes as you search - tracking keywords and search strings used in each database in order to avoid wasting time duplicating a search that has already been tried
  • Read abstracts and write down new terms to search as you find them
  • Check MeSH or other subject headings listed in relevant articles for additional search terms
  • Scan author provided keywords if available
  • Check the references of relevant articles looking for other useful articles (ancestry searching)
  • Check articles that have cited your relevant article for more useful articles (descendancy searching). Both PubMed and CINAHL offer Cited By links
  • Revise the search to broaden or narrow your topic focus as you peruse the available literature
  • Conducting a literature search is a repetitive process. Searches can be revised and re-run multiple times during the process.
  • Track the citations for your relevant articles in a software citation manager such as RefWorks, Zotero, or Mendeley

5. Review the literature

  • Read the full articles. Do not rely solely on the abstracts. Authors frequently cannot include all results within the confines of an abstract. Exclude articles that do not address your research question.
  • While reading, note research findings relevant to your project and summarize. Are the findings conflicting? There are matrices available than can help with organization. See the Organizing Information box below.
  • Critique / evaluate the quality of the articles, and record your findings in your matrix or summary table. Tools are available to prompt you what to look for. (See Resources for Appraising a Research Study box on the HSA, Nursing , and PA guides )
  • You may need to revise your search and re-run it based on your findings.

6. Organize and synthesize

  • Compile the findings and analysis from each resource into a single narrative.
  • Using an outline can be helpful. Start broad, addressing the overall findings and then narrow, discussing each resource and how it relates to your question and to the other resources.
  • Cite as you write to keep sources organized.
  • Write in structured paragraphs using topic sentences and transition words to draw connections, comparisons, and contrasts.
  • Don't present one study after another, but rather relate one study's findings to another. Speak to how the studies are connected and how they relate to your work.

Organizing Information

Options to assist in organizing sources and information :

1. Synthesis Matrix

  • helps provide overview of the literature
  • information from individual sources is entered into a grid to enable writers to discern patterns and themes
  • article summary, analysis, or results
  • thoughts, reflections, or issues
  • each reference gets its own row
  • mind maps, concept maps, flowcharts
  • at top of page record PICO or research question
  • record major concepts / themes from literature
  • list concepts that branch out from major concepts underneath - keep going downward hierarchically, until most specific ideas are recorded
  • enclose concepts in circles and connect the concept with lines - add brief explanation as needed

3. Summary Table

  • information is recorded in a grid to help with recall and sorting information when writing
  • allows comparing and contrasting individual studies easily
  • purpose of study
  • methodology (study population, data collection tool)

Efron, S. E., & Ravid, R. (2019). Writing the literature review : A practical guide . Guilford Press.

Literature Review Sections

  • Lit reviews can be part of a larger paper / research study or they can be the focus of the paper
  • Lit reviews focus on research studies to provide evidence
  • New topics may not have much that has been published

* The sections included may depend on the purpose of the literature review (standalone paper or section within a research paper)

Standalone Literature Review (aka Narrative Review):

  • presents your topic or PICO question
  • includes the why of the literature review and your goals for the review.
  • provides background for your the topic and previews the key points
  • Narrative Reviews: tmay not have an explanation of methods.
  • include where the search was conducted (which databases) what subject terms or keywords were used, and any limits or filters that were applied and why - this will help others re-create the search
  • describe how studies were analyzed for inclusion or exclusion
  • review the purpose and answer the research question
  • thematically - using recurring themes in the literature
  • chronologically - present the development of the topic over time
  • methodological - compare and contrast findings based on various methodologies used to research the topic (e.g. qualitative vs quantitative, etc.)
  • theoretical - organized content based on various theories
  • provide an overview of the main points of each source then synthesize the findings into a coherent summary of the whole
  • present common themes among the studies
  • compare and contrast the various study results
  • interpret the results and address the implications of the findings
  • do the results support the original hypothesis or conflict with it
  • provide your own analysis and interpretation (eg. discuss the significance of findings; evaluate the strengths and weaknesses of the studies, noting any problems)
  • discuss common and unusual patterns and offer explanations
  •  stay away from opinions, personal biases and unsupported recommendations
  • summarize the key findings and relate them back to your PICO/research question
  • note gaps in the research and suggest areas for further research
  • this section should not contain "new" information that had not been previously discussed in one of the sections above
  • provide a list of all the studies and other sources used in proper APA 7

Literature Review as Part of a Research Study Manuscript:

  • Compares the study with other research and includes how a study fills a gap in the research.
  • Focus on the body of the review which includes the synthesized Findings and Discussion

Literature Reviews vs Systematic Reviews

Systematic Reviews are NOT the same as a Literature Review:

Literature Reviews:

  • Literature reviews may or may not follow strict systematic methods to find, select, and analyze articles, but rather they selectively and broadly review the literature on a topic
  • Research included in a Literature Review can be "cherry-picked" and therefore, can be very subjective

Systematic Reviews:

  • Systemic reviews are designed to provide a comprehensive summary of the evidence for a focused research question
  • rigorous and strictly structured, using standardized reporting guidelines (e.g. PRISMA, see link below)
  • uses exhaustive, systematic searches of all relevant databases
  • best practice dictates search strategies are peer reviewed
  • uses predetermined study inclusion and exclusion criteria in order to minimize bias
  • aims to capture and synthesize all literature (including unpublished research - grey literature) that meet the predefined criteria on a focused topic resulting in high quality evidence

Literature Review Examples

  • Breastfeeding initiation and support: A literature review of what women value and the impact of early discharge (2017). Women and Birth : Journal of the Australian College of Midwives
  • Community-based participatory research to promote healthy diet and nutrition and prevent and control obesity among African-Americans: A literature review (2017). Journal of Racial and Ethnic Health Disparities

Systematic reviews provide a synthesis of evidence for a specific topic of interest, summarising the results of multiple studies to aid in clinical decisions and resource allocation. They remain among the best forms of evidence, and reduce the bias inherent in other methods. A solid understanding of the systematic review process can be of benefit to nurses that carry out such reviews, and for those who make decisions based on them. An overview of the main steps involved in carrying out a systematic review is presented, including some of the common tools and frameworks utilised in this area. This should provide a good starting point for those that are considering embarking on such work, and to aid readers of such reviews in their understanding of the main review components, in order to appraise the quality of a review that may be used to inform subsequent clinical decision making.

Since their inception in the late 1970s, systematic reviews have gained influence in the health professions ( Hanley and Cutts, 2013 ). Systematic reviews and meta-analyses are considered to be the most credible and authoritative sources of evidence available ( Cognetti et al, 2015 ) and are regarded as the pinnacle of evidence in the various ‘hierarchies of evidence’. Reviews published in the Cochrane Library ( https://www.cochranelibrary.com) are widely considered to be the ‘gold’ standard. Since Guyatt et al (1995) presented a users' guide to medical literature for the Evidence-Based Medicine Working Group, various hierarchies of evidence have been proposed. Figure 1 illustrates an example.

Systematic reviews can be qualitative or quantitative. One of the criticisms levelled at hierarchies such as these is that qualitative research is often positioned towards or even is at the bottom of the pyramid, thus implying that it is of little evidential value. This may be because of traditional issues concerning the quality of some qualitative work, although it is now widely recognised that both quantitative and qualitative research methodologies have a valuable part to play in answering research questions, which is reflected by the National Institute for Health and Care Excellence (NICE) information concerning methods for developing public health guidance. The NICE (2012) guidance highlights how both qualitative and quantitative study designs can be used to answer different research questions. In a revised version of the hierarchy-of-evidence pyramid, the systematic review is considered as the lens through which the evidence is viewed, rather than being at the top of the pyramid ( Murad et al, 2016 ).

Both quantitative and qualitative research methodologies are sometimes combined in a single review. According to the Cochrane review handbook ( Higgins and Green, 2011 ), regardless of type, reviews should contain certain features, including:

  • Clearly stated objectives
  • Predefined eligibility criteria for inclusion or exclusion of studies in the review
  • A reproducible and clearly stated methodology
  • Validity assessment of included studies (eg quality, risk, bias etc).

The main stages of carrying out a systematic review are summarised in Box 1 .

Formulating the research question

Before undertaking a systemic review, a research question should first be formulated ( Bashir and Conlon, 2018 ). There are a number of tools/frameworks ( Table 1 ) to support this process, including the PICO/PICOS, PEO and SPIDER criteria ( Bowers et al, 2011 ). These frameworks are designed to help break down the question into relevant subcomponents and map them to concepts, in order to derive a formalised search criterion ( Methley et al, 2014 ). This stage is essential for finding literature relevant to the question ( Jahan et al, 2016 ).

It is advisable to first check that the review you plan to carry out has not already been undertaken. You can optionally register your review with an international register of prospective reviews called PROSPERO, although this is not essential for publication. This is done to help you and others to locate work and see what reviews have already been carried out in the same area. It also prevents needless duplication and instead encourages building on existing work ( Bashir and Conlon, 2018 ).

A study ( Methley et al, 2014 ) that compared PICO, PICOS and SPIDER in relation to sensitivity and specificity recommended that the PICO tool be used for a comprehensive search and the PICOS tool when time/resources are limited.

The use of the SPIDER tool was not recommended due to the risk of missing relevant papers. It was, however, found to increase specificity.

These tools/frameworks can help those carrying out reviews to structure research questions and define key concepts in order to efficiently identify relevant literature and summarise the main objective of the review ( Jahan et al, 2016 ). A possible research question could be: Is paracetamol of benefit to people who have just had an operation? The following examples highlight how using a framework may help to refine the question:

  • What form of paracetamol? (eg, oral/intravenous/suppository)
  • Is the dosage important?
  • What is the patient population? (eg, children, adults, Europeans)
  • What type of operation? (eg, tonsillectomy, appendectomy)
  • What does benefit mean? (eg, reduce post-operative pyrexia, analgesia).

An example of a more refined research question could be: Is oral paracetamol effective in reducing pain following cardiac surgery for adult patients? A number of concepts for each element will need to be specified. There will also be a number of synonyms for these concepts ( Table 2 ).

Table 2 shows an example of concepts used to define a search strategy using the PICO statement. It is easy to see even with this dummy example that there are many concepts that require mapping and much thought required to capture ‘good’ search criteria. Consideration should be given to the various terms to describe the heart, such as cardiac, cardiothoracic, myocardial, myocardium, etc, and the different names used for drugs, such as the equivalent name used for paracetamol in other countries and regions, as well as the various brand names. Defining good search criteria is an important skill that requires a lot of practice. A high-quality review gives details of the search criteria that enables the reader to understand how the authors came up with the criteria. A specific, well-defined search criterion also aids in the reproducibility of a review.

Search criteria

Before the search for papers and other documents can begin it is important to explicitly define the eligibility criteria to determine whether a source is relevant to the review ( Hanley and Cutts, 2013 ). There are a number of database sources that are searched for medical/health literature including those shown in Table 3 .

The various databases can be searched using common Boolean operators to combine or exclude search terms (ie AND, OR, NOT) ( Figure 2 ).

literature review nursing examples

Although most literature databases use similar operators, it is necessary to view the individual database guides, because there are key differences between some of them. Table 4 details some of the common operators and wildcards used in the databases for searching. When developing a search criteria, it is a good idea to check concepts against synonyms, as well as abbreviations, acronyms and plural and singular variations ( Cognetti et al, 2015 ). Reading some key papers in the area and paying attention to the key words they use and other terms used in the abstract, and looking through the reference lists/bibliographies of papers, can also help to ensure that you incorporate relevant terms. Medical Subject Headings (MeSH) that are used by the National Library of Medicine (NLM) ( https://www.nlm.nih.gov/mesh/meshhome.html) to provide hierarchical biomedical index terms for NLM databases (Medline and PubMed) should also be explored and included in relevant search strategies.

Searching the ‘grey literature’ is also an important factor in reducing publication bias. It is often the case that only studies with positive results and statistical significance are published. This creates a certain bias inherent in the published literature. This bias can, to some degree, be mitigated by the inclusion of results from the so-called grey literature, including unpublished work, abstracts, conference proceedings and PhD theses ( Higgins and Green, 2011 ; Bettany-Saltikov, 2012 ; Cognetti et al, 2015 ). Biases in a systematic review can lead to overestimating or underestimating the results ( Jahan et al, 2016 ).

An example search strategy from a published review looking at web use for the appraisal of physical health conditions can be seen in Box 2 . High-quality reviews usually detail which databases were searched and the number of items retrieved from each.

A balance between high recall and high precision is often required in order to produce the best results. An oversensitive search, or one prone to including too much noise, can mean missing important studies or producing too many search results ( Cognetti et al, 2015 ). Following a search, the exported citations can be added to citation management software (such as Mendeley or Endnote) and duplicates removed.

Title and abstract screening

Initial screening begins with the title and abstracts of articles being read and included or excluded from the review based on their relevance. This is usually carried out by at least two researchers to reduce bias ( Bashir and Conlon, 2018 ). After screening any discrepancies in agreement should be resolved by discussion, or by an additional researcher casting the deciding vote ( Bashir and Conlon, 2018 ). Statistics for inter-rater reliability exist and can be reported, such as percentage of agreement or Cohen's kappa ( Box 3 ) for two reviewers and Fleiss' kappa for more than two reviewers. Agreement can depend on the background and knowledge of the researchers and the clarity of the inclusion and exclusion criteria. This highlights the importance of providing clear, well-defined criteria for inclusion that are easy for other researchers to follow.

Full-text review

Following title and abstract screening, the remaining articles/sources are screened in the same way, but this time the full texts are read in their entirety and included or excluded based on their relevance. Reasons for exclusion are usually recorded and reported. Extraction of the specific details of the studies can begin once the final set of papers is determined.

Data extraction

At this stage, the full-text papers are read and compared against the inclusion criteria of the review. Data extraction sheets are forms that are created to extract specific data about a study (12 Jahan et al, 2016 ) and ensure that data are extracted in a uniform and structured manner. Extraction sheets can differ between quantitative and qualitative reviews. For quantitative reviews they normally include details of the study's population, design, sample size, intervention, comparisons and outcomes ( Bettany-Saltikov, 2012 ; Mueller et al, 2017 ).

Quality appraisal

The quality of the studies used in the review should also be appraised. Caldwell et al (2005) discussed the need for a health research evaluation framework that could be used to evaluate both qualitative and quantitative work. The framework produced uses features common to both research methodologies, as well as those that differ ( Caldwell et al, 2005 ; Dixon-Woods et al, 2006 ). Figure 3 details the research critique framework. Other quality appraisal methods do exist, such as those presented in Box 4 . Quality appraisal can also be used to weight the evidence from studies. For example, more emphasis can be placed on the results of large randomised controlled trials (RCT) than one with a small sample size. The quality of a review can also be used as a factor for exclusion and can be specified in inclusion/exclusion criteria. Quality appraisal is an important step that needs to be undertaken before conclusions about the body of evidence can be made ( Sambunjak and Franic, 2012 ). It is also important to note that there is a difference between the quality of the research carried out in the studies and the quality of how those studies were reported ( Sambunjak and Franic, 2012 ).

literature review nursing examples

The quality appraisal is different for qualitative and quantitative studies. With quantitative studies this usually focuses on their internal and external validity, such as how well the study has been designed and analysed, and the generalisability of its findings. Qualitative work, on the other hand, is often evaluated in terms of trustworthiness and authenticity, as well as how transferable the findings may be ( Bettany-Saltikov, 2012 ; Bashir and Conlon, 2018 ; Siddaway et al, 2019 ).

Reporting a review (the PRISMA statement)

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) provides a reporting structure for systematic reviews/meta-analysis, and consists of a checklist and diagram ( Figure 4 ). The stages of identifying potential papers/sources, screening by title and abstract, determining eligibility and final inclusion are detailed with the number of articles included/excluded at each stage. PRISMA diagrams are often included in systematic reviews to detail the number of papers included at each of the four main stages (identification, screening, eligibility and inclusion) of the review.

Data synthesis

The combined results of the screened studies can be analysed qualitatively by grouping them together under themes and subthemes, often referred to as meta-synthesis or meta-ethnography ( Siddaway et al, 2019 ). Sometimes this is not done and a summary of the literature found is presented instead. When the findings are synthesised, they are usually grouped into themes that were derived by noting commonality among the studies included. Inductive (bottom-up) thematic analysis is frequently used for such purposes and works by identifying themes (essentially repeating patterns) in the data, and can include a set of higher-level and related subthemes (Braun and Clarke, 2012). Thomas and Harden (2008) provide examples of the use of thematic synthesis in systematic reviews, and there is an excellent introduction to thematic analysis by Braun and Clarke (2012).

The results of the review should contain details on the search strategy used (including search terms), the databases searched (and the number of items retrieved), summaries of the studies included and an overall synthesis of the results ( Bettany-Saltikov, 2012 ). Finally, conclusions should be made about the results and the limitations of the studies included ( Jahan et al, 2016 ). Another method for synthesising data in a systematic review is a meta-analysis.

Limitations of systematic reviews

Apart from the many advantages and benefits to carrying out systematic reviews highlighted throughout this article, there remain a number of disadvantages. These include the fact that not all stages of the review process are followed rigorously or even at all in some cases. This can lead to poor quality reviews that are difficult or impossible to replicate. There also exist some barriers to the use of evidence produced by reviews, including ( Wallace et al, 2012 ):

  • Lack of awareness and familiarity with reviews
  • Lack of access
  • Lack of direct usefulness/applicability.

Meta-analysis

When the methods used and the analysis are similar or the same, such as in some RCTs, the results can be synthesised using a statistical approach called meta-analysis and presented using summary visualisations such as forest plots (or blobbograms) ( Figure 5 ). This can be done only if the results can be combined in a meaningful way.

literature review nursing examples

Meta-analysis can be carried out using common statistical and data science software, such as the cross-platform ‘R’ ( https://www.r-project.org), or by using standalone software, such as Review Manager (RevMan) produced by the Cochrane community ( https://tinyurl.com/revman-5), which is currently developing a cross-platform version RevMan Web.

Carrying out a systematic review is a time-consuming process, that on average takes between 6 and 18 months and requires skill from those involved. Ideally, several reviewers will work on a review to reduce bias. Experts such as librarians should be consulted and included where possible in review teams to leverage their expertise.

Systematic reviews should present the state of the art (most recent/up-to-date developments) concerning a specific topic and aim to be systematic and reproducible. Reproducibility is aided by transparent reporting of the various stages of a review using reporting frameworks such as PRISMA for standardisation. A high-quality review should present a summary of a specific topic to a high standard upon which other professionals can base subsequent care decisions that increase the quality of evidence-based clinical practice.

  • Systematic reviews remain one of the most trusted sources of high-quality information from which to make clinical decisions
  • Understanding the components of a review will help practitioners to better assess their quality
  • Many formal frameworks exist to help structure and report reviews, the use of which is recommended for reproducibility
  • Experts such as librarians can be included in the review team to help with the review process and improve its quality

CPD reflective questions

  • Where should high-quality qualitative research sit regarding the hierarchies of evidence?
  • What background and expertise should those conducting a systematic review have, and who should ideally be included in the team?
  • Consider to what extent inter-rater agreement is important in the screening process

The Scholarly Conversation

A literature review provides an overview of previous research on a topic that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps map the different approaches to a given question and reveals patterns. It forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

  • The format is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
  • The introduction should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
  • In the body of the review, the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
  • The conclusion will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
  • The list of references will include full citations for all of the items mentioned in the literature review.

A literature review should try to answer questions such as

  • Who are the key researchers on this topic?
  • What has been the focus of the research efforts so far and what is the current status?
  • How have certain studies built on prior studies? Where are the connections? Are there new interpretations of the research?
  • Have there been any controversies or debate about the research? Is there consensus? Are there any contradictions?
  • Which areas have been identified as needing further research? Have any pathways been suggested?
  • How will your topic uniquely contribute to this body of knowledge?
  • Which methodologies have researchers used and which appear to be the most productive?
  • What sources of information or data were identified that might be useful to you?
  • How does your particular topic fit into the larger context of what has already been done?
  • How has the research that has already been done help frame your current investigation ?

It uses uncomplicated language to signpost the reader effortlessly through key aspects of research processes. Practitioners will find this an invaluable companion for navigating through evidence to identify quality literature applicable to health and social care practice.' 

'Students often struggle with writing an effective literature review and this invaluable guide will help to allay their concerns. Key terms are clearly explained, and the inclusion of learning outcomes is a helpful feature for students and lecturers alike.  The examples are also very helpful, particularly for less confident students.  This is an accessible yet authoritative guide which I can thoroughly recommend.' 

'A must have - this book provides useful information and guidance to students and professionals alike. It guides the reader through various research methods in a theoretical and pragmatic manner.' 

' It's a very readable, concise, and accessible introduction to undertaking a literature review in the field of healthcare. The book’s layout has a logical format which really helped me to think methodically about my research question. An excellent reference for undergraduates who are about to undertake their first literature review.' 

'This book is an essential resource for students. Clearly written and excellently structured, with helpful study tools throughout, it takes the reader step by step through the literature review process in an easy, informative and accessible manner. This text gives students the skills they need to successfully complete their own review.' 

'The updating of the chapters will be exceptionally helpful given the rapid changes in online availability of resources and open-access literature.'  

Excellent text for masters and doctoral level students

An excellent primer to help the level 7 students write their systemised review for the assignment.

This book provides a comprehensive overview of the practical process of literature review in healthcare. It contains all details required to conduct a review by students.

This is an excellent clear and concise book on undertaking literature reviews being particularly good at demystifying jargon. It is timely given the move to student dissertations being primarily literature reviews in the current Covid pandemic. However nearly all the examples are drawn from nursing and health making the text less useful for social care and social work. A little disappointing given the title. SW students are likely to gravitate to texts where their subject is more prominent for a primary text.

Accessible, informative, step to step guide

This is a really helpful, accessible text for students and academic staff alike.

A really good addition to the repertoire of skills and techniques for understanding the essential process of literature reviewing.

How to undertake a literature search

Introduction.

Undertaking a literature search can be a daunting prospect. By breaking the exercise down into smaller steps, you can make the process more manageable. The following ten steps will help you complete the task from identifying key concepts to choosing databases for your search and saving your results and search strategy. It discusses each of the steps in a little more detail with examples and suggestions of where to get help.

There are ten steps to undertaking a literature search which we'll take you through below:

🎬 - Indicates a video is available with more information.

Please click on the boxes below to get a bit more detail on each step.

First, write out your title and check that you understand all the terms. Look up the meaning of any you don’t understand. An online dictionary or medical encyclopaedia may help with this.

If your search is for a dissertation, you may need to choose your own research question. In this case, you will need to consider whether there is likely to be enough research on your topic. Alternatively, if your topic is too broad, you could be overwhelmed by the number of references.

One way of checking how much is written on your topic is to use Library Search. Most libraries offer a Library Search or discovery tool. It provides a quick search across all the library’s holdings. You can also limit your search by date or type of document. If you just need a few references to help you write an essay, Library Search may be helpful. It also gives quick access to full text items.

Next, you need to identify your key concepts. One way to do this is to look at your title and identify the most important words. Ignore words that tell you what to do with the information you find eg evaluate, assess, compare, as these are not generally used as search terms. In the example below, key concepts have been highlighted:

Evaluate the effectiveness of a mindfulness intervention on the health-related quality of life of rheumatoid arthritis patients

Another way to do this is to break down your title using the PEO framework:

P = Population    E = Exposure    O = Outcome 

This works well where there is no comparison between two types of treatment or intervention.

In our example:

P = rheumatoid arthritis patients

E = mindfulness

O =  health related quality of life

Other question formats are available such as PICO or SPIDER

Tip: Not all search topics will include every element of PICO – some include fewer items.

Once you have identified the key concepts, it’s important to think of any other terms or phrases that might have a very similar meaning. Including such synonyms will make your search as thorough as possible. For example, if your topic is looking for articles on Staff attitudes , you might also use the terms:

  • Staff perceptions 
  • Staff opinions
  • Stereotyping
  • Labelling 

If the database you are using has a list of subject heading s , this may help you to find the most appropriate term for your subject. Some databases provide definitions for terms used in the database and may suggest related terms.

A comprehensive search will usually include both subject headings from databases and terms that you have thought of yourself.

Tip: Often your search term will be a phrase instead of a single word. To carry out phrase searches, use double quotes, for example “problem drinking”.

Once you have chosen your search terms, you need to think about the best databases for your topic. The databases you choose will depend on the search question and the libraries you have access to.

Tip: It’s well worth taking a few minutes to get to know the databases available on the Library webpages and what they cover.

The next step is to combine your search terms in such a way that you only retrieve the more relevant references for your search question. In order to do this you need to build a search strategy . This involves using Boolean operators such as AND , OR and NOT .

AND narrows the results of the search by ensuring that all the search terms are present in the results. 

OR broadens the results of the search by ensuring that any of the search terms are present in the results.

NOT limits the results by rejecting a particular search term. Be careful with NOT because it will exclude any results containing that search term regardless of whether other parts of the article might have been of interest.

OR will broaden your number of results while AND will produce fewer results.

Try using this  Search-plan-worksheet   to break your topic down into concepts. These can then be linked together when you run the search. You can also add synonyms within each concept box. The yellow limits box is a prompt to think about any limits you want to apply when searching. This leads us to Step 6.

Tip: Most databases will allow you to use a truncation sign (*) or wildcard (?) to pick up various different endings to words or alternative spellings.

For example:  alcohol* would pick up alcohol, alcoholic, alcoholism, etc

Sm?th would find Smith and Smyth

The next step is to think about any other restrictions you want to make to your results.

Common limiters found on databases include:

  • Peer reviewed articles
  • Research articles
  • Age group (adult, child, older person)
  • Document type

Not all databases allow all of the limiters above.

When writing a dissertation, primary research articles are normally required. Where the database allows you, try limiting to research articles only.

Non-research materials can also be useful as an overview of your topic; for example a literature review can give an analysis of what has already been written on a topic.

The video below includes a demonstration of how limits can be applied using the CINAHL database as an example:

CINAHL - advanced

Once you have identified all your search terms and any limits you want to apply, you are ready to run your search on the databases you have chosen. 

Once you have some search results, you can look through them and start to select those that look relevant to your literature search. It is likely you will reject some because they are not quite what you wanted but there will be others that can be marked for further attention.

The title of an article on its own may not tell you very much; read the abstract quite carefully to see if the article is relevant or not.

Tip: You can show more details for each record by clicking on the article title. On some databases, there may be an abstract for the article which you can open. 

If you find you are either generating more results than you can possibly look at or too few results to write about, be prepared to adjust your search terms and the way they are combined.

If you get too many results you could try: •limiting to just the most recent material •adding another term or concept and linking it using “AND” •limiting to a particular country or geographical area such as UK

If you get too few results, you might try: •expanding your date range •removing any geographical limits you have applied  •removing the least important term or concept

Tip: Be prepared to try other databases and keep searching until you feel confident you have found enough relevant material.

Once you have selected some articles that look relevant for your piece of work, you will need to save them so that your hard work is not wasted.

At the same time, you will want to save your search strategy . This is a record of the terms you searched, how you combined them, any limits you applied and how many results you found.

You will also need to choose a way to save your results. One way is to email the results to yourself and this can be done from all the databases .

Another way is to export your results to reference management software such as Zotero, RefWorks, EndNote or Mendeley. This software allows you to collect, organise and cite research. It is suitable for managing references over a long period of time. 

The RCN Library and Archive Service provides help with using Zotero . 

Tip: Keep a record of all the databases you use as you carry out your search. It is also a good idea to note where you found any references you subsequently use for your dissertation.

The final step is to obtain the full text of the articles identified in your search which you believe may be useful for your assignment. If you are lucky, many of these will be available electronically and you may just be able to follow a link to the full text.

Alternatively you can copy and paste your article title into the Library search box  and if it is available as full text, a hyperlink will be shown which will link you to the document.

If you are studying elsewhere and have access to a university or hospital library, they may subscribe to different journals to the RCN Library so it is worth exploring what they can offer. If your library does not have either an electronic copy or a physical copy, you may need to request the article by interlibrary loan .

Tip: It is also worth using Google or other browsers to check for the article title you require. Sometimes the article has been made freely available on the internet by the authors.

Boolean operators – words (AND, OR and NOT) which can be used to combine search terms in order to widen or limit the search results.

Database – this is an online collection of citations to journal articles which have been indexed to make retrieval easier. Some databases which also provide full text access to the articles.

Limits – these are options within a database which allow search results to be broken down further. Common limits are year(s) of publication, document type and language. MEDLINE and CINAHL allow age limits too.

Search Strategy – the list of search terms and limits used to retrieve relevant articles from a database in order to answer a search question.

Subject headings – terms that have been assigned to describe a concept that may have many alternative keywords. All these alternative keywords or terms are brought together under the umbrella of this single term. Most health-related databases use subject headings.

Nursing Literature Reviews

What is a Literature (Lit) Review? 

A Literature Review is Not: 

  • a quick summary of sources
  • a grouping of broad, unrelated sources
  • a compilation of everything that has ever been written on a topic
  • a literature criticism or book review

So, what is it then?

A literature review is an integrated analysis-- not just a summary-- of scholarly writings that are related directly to your research question.  That is, it represents the literature that provides background information on your topic and shows a correspondence between those writings and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

  • Explains the background of research on a topic.
  • Demonstrates why a topic is significant to a subject area.
  • Discovers relationships between research studies/ideas.
  • Identifies major themes, concepts, and researchers on a topic.
  • Identifies critical gaps and points of disagreement.
  • Discusses further research questions that logically come out of the previous studies.

Creating a Literature Review using the Matrix Method: 

A matrix review allows you to quickly compare and contrast articles in an easy to read format. It can help you to easily spot differences and similarities between journal articles and your nursing research topic. Review matrices are especially helpful for health sciences literature reviews that cover the scope of research over a given amount of time. 

Most literature reviews are set up in this format:

Steps for Conducting a Literature Review

1. Choose Your Topic

  • Review your PICO question and think about your central research question. To review the PICO process, please see Kerry Sewell's LibGuide on this subject. 

2. Decide on the scope of your review

  • How many studies do you need to look at? 
  • How comprehensive should it be? 
  • How many years should it cover? 

3. Select the databases you want to use to conduct your searches (See the Databases Tab Above!)

4. Conduct your searches and find the literature. (Keep track of your searches, try using the Search Strategy Lab Notebook!)

  • Review the abstracts and conclusions carefully. This will help you decide which articles actually fit the criteria you are looking for. 
  • Write down the keywords you used and where you found them. 
  • You can also use RefWorks to keep track of your citations. 

5. Review the Literature (This will probably be the most time consuming part)

  • What was the research question of the study you are reviewing?  What were the authors trying to discover? 
  • Was the research funded by a company or source that could influence the findings? (Such as Colgate® sponsoring a toothpaste study?)
  • What were the research methodologies? Analyze the paper's literature review, the samples and variables used, the results and conclusions. Does the research seem to be complete? Could it have been conducted more soundly? What questions does it raise? 
  • If there are conflicting studies, why do you think that is? 
  • How are the authors of the paper viewed in the field? Has this study been cited by other publications? 

Literature Review Examples

Remember, a lit review provides an intelligent overview of the topic. There may or may not be a method for how studies are collected or interpreted. Lit reviews aren't always labeled specifically as "literature reviews," they may often be embedded with other sections such as an introduction or background.

What is a Literature Review?

The Scholarly Conversation

A literature review provides an overview of previous research on a topic  that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps  map the different approaches to a given question and reveals  patterns.  It  forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

  • The  format  is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
  • The  introduction  should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
  • In the  body of the review , the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
  • The  conclusion  will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
  • The  list of references  will include full citations for all of the items mentioned in the literature review.

Chapter 9 methods for literature reviews.

Guy Paré and Spyros Kitsiou .

9.1. Introduction

Literature reviews play a critical role in scholarship because science remains, first and foremost, a cumulative endeavour ( vom Brocke et al., 2009 ). As in any academic discipline, rigorous knowledge syntheses are becoming indispensable in keeping up with an exponentially growing eHealth literature, assisting practitioners, academics, and graduate students in finding, evaluating, and synthesizing the contents of many empirical and conceptual papers. Among other methods, literature reviews are essential for: (a) identifying what has been written on a subject or topic; (b) determining the extent to which a specific research area reveals any interpretable trends or patterns; (c) aggregating empirical findings related to a narrow research question to support evidence-based practice; (d) generating new frameworks and theories; and (e) identifying topics or questions requiring more investigation ( Paré, Trudel, Jaana, & Kitsiou, 2015 ).

Literature reviews can take two major forms. The most prevalent one is the “literature review” or “background” section within a journal paper or a chapter in a graduate thesis. This section synthesizes the extant literature and usually identifies the gaps in knowledge that the empirical study addresses ( Sylvester, Tate, & Johnstone, 2013 ). It may also provide a theoretical foundation for the proposed study, substantiate the presence of the research problem, justify the research as one that contributes something new to the cumulated knowledge, or validate the methods and approaches for the proposed study ( Hart, 1998 ; Levy & Ellis, 2006 ).

The second form of literature review, which is the focus of this chapter, constitutes an original and valuable work of research in and of itself ( Paré et al., 2015 ). Rather than providing a base for a researcher’s own work, it creates a solid starting point for all members of the community interested in a particular area or topic ( Mulrow, 1987 ). The so-called “review article” is a journal-length paper which has an overarching purpose to synthesize the literature in a field, without collecting or analyzing any primary data ( Green, Johnson, & Adams, 2006 ).

When appropriately conducted, review articles represent powerful information sources for practitioners looking for state-of-the art evidence to guide their decision-making and work practices ( Paré et al., 2015 ). Further, high-quality reviews become frequently cited pieces of work which researchers seek out as a first clear outline of the literature when undertaking empirical studies ( Cooper, 1988 ; Rowe, 2014 ). Scholars who track and gauge the impact of articles have found that review papers are cited and downloaded more often than any other type of published article ( Cronin, Ryan, & Coughlan, 2008 ; Montori, Wilczynski, Morgan, Haynes, & Hedges, 2003 ; Patsopoulos, Analatos, & Ioannidis, 2005 ). The reason for their popularity may be the fact that reading the review enables one to have an overview, if not a detailed knowledge of the area in question, as well as references to the most useful primary sources ( Cronin et al., 2008 ). Although they are not easy to conduct, the commitment to complete a review article provides a tremendous service to one’s academic community ( Paré et al., 2015 ; Petticrew & Roberts, 2006 ). Most, if not all, peer-reviewed journals in the fields of medical informatics publish review articles of some type.

The main objectives of this chapter are fourfold: (a) to provide an overview of the major steps and activities involved in conducting a stand-alone literature review; (b) to describe and contrast the different types of review articles that can contribute to the eHealth knowledge base; (c) to illustrate each review type with one or two examples from the eHealth literature; and (d) to provide a series of recommendations for prospective authors of review articles in this domain.

9.2. Overview of the Literature Review Process and Steps

As explained in Templier and Paré (2015) , there are six generic steps involved in conducting a review article:

  • formulating the research question(s) and objective(s),
  • searching the extant literature,
  • screening for inclusion,
  • assessing the quality of primary studies,
  • extracting data, and
  • analyzing data.

Although these steps are presented here in sequential order, one must keep in mind that the review process can be iterative and that many activities can be initiated during the planning stage and later refined during subsequent phases ( Finfgeld-Connett & Johnson, 2013 ; Kitchenham & Charters, 2007 ).

Formulating the research question(s) and objective(s): As a first step, members of the review team must appropriately justify the need for the review itself ( Petticrew & Roberts, 2006 ), identify the review’s main objective(s) ( Okoli & Schabram, 2010 ), and define the concepts or variables at the heart of their synthesis ( Cooper & Hedges, 2009 ; Webster & Watson, 2002 ). Importantly, they also need to articulate the research question(s) they propose to investigate ( Kitchenham & Charters, 2007 ). In this regard, we concur with Jesson, Matheson, and Lacey (2011) that clearly articulated research questions are key ingredients that guide the entire review methodology; they underscore the type of information that is needed, inform the search for and selection of relevant literature, and guide or orient the subsequent analysis. Searching the extant literature: The next step consists of searching the literature and making decisions about the suitability of material to be considered in the review ( Cooper, 1988 ). There exist three main coverage strategies. First, exhaustive coverage means an effort is made to be as comprehensive as possible in order to ensure that all relevant studies, published and unpublished, are included in the review and, thus, conclusions are based on this all-inclusive knowledge base. The second type of coverage consists of presenting materials that are representative of most other works in a given field or area. Often authors who adopt this strategy will search for relevant articles in a small number of top-tier journals in a field ( Paré et al., 2015 ). In the third strategy, the review team concentrates on prior works that have been central or pivotal to a particular topic. This may include empirical studies or conceptual papers that initiated a line of investigation, changed how problems or questions were framed, introduced new methods or concepts, or engendered important debate ( Cooper, 1988 ). Screening for inclusion: The following step consists of evaluating the applicability of the material identified in the preceding step ( Levy & Ellis, 2006 ; vom Brocke et al., 2009 ). Once a group of potential studies has been identified, members of the review team must screen them to determine their relevance ( Petticrew & Roberts, 2006 ). A set of predetermined rules provides a basis for including or excluding certain studies. This exercise requires a significant investment on the part of researchers, who must ensure enhanced objectivity and avoid biases or mistakes. As discussed later in this chapter, for certain types of reviews there must be at least two independent reviewers involved in the screening process and a procedure to resolve disagreements must also be in place ( Liberati et al., 2009 ; Shea et al., 2009 ). Assessing the quality of primary studies: In addition to screening material for inclusion, members of the review team may need to assess the scientific quality of the selected studies, that is, appraise the rigour of the research design and methods. Such formal assessment, which is usually conducted independently by at least two coders, helps members of the review team refine which studies to include in the final sample, determine whether or not the differences in quality may affect their conclusions, or guide how they analyze the data and interpret the findings ( Petticrew & Roberts, 2006 ). Ascribing quality scores to each primary study or considering through domain-based evaluations which study components have or have not been designed and executed appropriately makes it possible to reflect on the extent to which the selected study addresses possible biases and maximizes validity ( Shea et al., 2009 ). Extracting data: The following step involves gathering or extracting applicable information from each primary study included in the sample and deciding what is relevant to the problem of interest ( Cooper & Hedges, 2009 ). Indeed, the type of data that should be recorded mainly depends on the initial research questions ( Okoli & Schabram, 2010 ). However, important information may also be gathered about how, when, where and by whom the primary study was conducted, the research design and methods, or qualitative/quantitative results ( Cooper & Hedges, 2009 ). Analyzing and synthesizing data : As a final step, members of the review team must collate, summarize, aggregate, organize, and compare the evidence extracted from the included studies. The extracted data must be presented in a meaningful way that suggests a new contribution to the extant literature ( Jesson et al., 2011 ). Webster and Watson (2002) warn researchers that literature reviews should be much more than lists of papers and should provide a coherent lens to make sense of extant knowledge on a given topic. There exist several methods and techniques for synthesizing quantitative (e.g., frequency analysis, meta-analysis) and qualitative (e.g., grounded theory, narrative analysis, meta-ethnography) evidence ( Dixon-Woods, Agarwal, Jones, Young, & Sutton, 2005 ; Thomas & Harden, 2008 ).

9.3. Types of Review Articles and Brief Illustrations

EHealth researchers have at their disposal a number of approaches and methods for making sense out of existing literature, all with the purpose of casting current research findings into historical contexts or explaining contradictions that might exist among a set of primary research studies conducted on a particular topic. Our classification scheme is largely inspired from Paré and colleagues’ (2015) typology. Below we present and illustrate those review types that we feel are central to the growth and development of the eHealth domain.

9.3.1. Narrative Reviews

The narrative review is the “traditional” way of reviewing the extant literature and is skewed towards a qualitative interpretation of prior knowledge ( Sylvester et al., 2013 ). Put simply, a narrative review attempts to summarize or synthesize what has been written on a particular topic but does not seek generalization or cumulative knowledge from what is reviewed ( Davies, 2000 ; Green et al., 2006 ). Instead, the review team often undertakes the task of accumulating and synthesizing the literature to demonstrate the value of a particular point of view ( Baumeister & Leary, 1997 ). As such, reviewers may selectively ignore or limit the attention paid to certain studies in order to make a point. In this rather unsystematic approach, the selection of information from primary articles is subjective, lacks explicit criteria for inclusion and can lead to biased interpretations or inferences ( Green et al., 2006 ). There are several narrative reviews in the particular eHealth domain, as in all fields, which follow such an unstructured approach ( Silva et al., 2015 ; Paul et al., 2015 ).

Despite these criticisms, this type of review can be very useful in gathering together a volume of literature in a specific subject area and synthesizing it. As mentioned above, its primary purpose is to provide the reader with a comprehensive background for understanding current knowledge and highlighting the significance of new research ( Cronin et al., 2008 ). Faculty like to use narrative reviews in the classroom because they are often more up to date than textbooks, provide a single source for students to reference, and expose students to peer-reviewed literature ( Green et al., 2006 ). For researchers, narrative reviews can inspire research ideas by identifying gaps or inconsistencies in a body of knowledge, thus helping researchers to determine research questions or formulate hypotheses. Importantly, narrative reviews can also be used as educational articles to bring practitioners up to date with certain topics of issues ( Green et al., 2006 ).

Recently, there have been several efforts to introduce more rigour in narrative reviews that will elucidate common pitfalls and bring changes into their publication standards. Information systems researchers, among others, have contributed to advancing knowledge on how to structure a “traditional” review. For instance, Levy and Ellis (2006) proposed a generic framework for conducting such reviews. Their model follows the systematic data processing approach comprised of three steps, namely: (a) literature search and screening; (b) data extraction and analysis; and (c) writing the literature review. They provide detailed and very helpful instructions on how to conduct each step of the review process. As another methodological contribution, vom Brocke et al. (2009) offered a series of guidelines for conducting literature reviews, with a particular focus on how to search and extract the relevant body of knowledge. Last, Bandara, Miskon, and Fielt (2011) proposed a structured, predefined and tool-supported method to identify primary studies within a feasible scope, extract relevant content from identified articles, synthesize and analyze the findings, and effectively write and present the results of the literature review. We highly recommend that prospective authors of narrative reviews consult these useful sources before embarking on their work.

Darlow and Wen (2015) provide a good example of a highly structured narrative review in the eHealth field. These authors synthesized published articles that describe the development process of mobile health ( m-health ) interventions for patients’ cancer care self-management. As in most narrative reviews, the scope of the research questions being investigated is broad: (a) how development of these systems are carried out; (b) which methods are used to investigate these systems; and (c) what conclusions can be drawn as a result of the development of these systems. To provide clear answers to these questions, a literature search was conducted on six electronic databases and Google Scholar . The search was performed using several terms and free text words, combining them in an appropriate manner. Four inclusion and three exclusion criteria were utilized during the screening process. Both authors independently reviewed each of the identified articles to determine eligibility and extract study information. A flow diagram shows the number of studies identified, screened, and included or excluded at each stage of study selection. In terms of contributions, this review provides a series of practical recommendations for m-health intervention development.

9.3.2. Descriptive or Mapping Reviews

The primary goal of a descriptive review is to determine the extent to which a body of knowledge in a particular research topic reveals any interpretable pattern or trend with respect to pre-existing propositions, theories, methodologies or findings ( King & He, 2005 ; Paré et al., 2015 ). In contrast with narrative reviews, descriptive reviews follow a systematic and transparent procedure, including searching, screening and classifying studies ( Petersen, Vakkalanka, & Kuzniarz, 2015 ). Indeed, structured search methods are used to form a representative sample of a larger group of published works ( Paré et al., 2015 ). Further, authors of descriptive reviews extract from each study certain characteristics of interest, such as publication year, research methods, data collection techniques, and direction or strength of research outcomes (e.g., positive, negative, or non-significant) in the form of frequency analysis to produce quantitative results ( Sylvester et al., 2013 ). In essence, each study included in a descriptive review is treated as the unit of analysis and the published literature as a whole provides a database from which the authors attempt to identify any interpretable trends or draw overall conclusions about the merits of existing conceptualizations, propositions, methods or findings ( Paré et al., 2015 ). In doing so, a descriptive review may claim that its findings represent the state of the art in a particular domain ( King & He, 2005 ).

In the fields of health sciences and medical informatics, reviews that focus on examining the range, nature and evolution of a topic area are described by Anderson, Allen, Peckham, and Goodwin (2008) as mapping reviews . Like descriptive reviews, the research questions are generic and usually relate to publication patterns and trends. There is no preconceived plan to systematically review all of the literature although this can be done. Instead, researchers often present studies that are representative of most works published in a particular area and they consider a specific time frame to be mapped.

An example of this approach in the eHealth domain is offered by DeShazo, Lavallie, and Wolf (2009). The purpose of this descriptive or mapping review was to characterize publication trends in the medical informatics literature over a 20-year period (1987 to 2006). To achieve this ambitious objective, the authors performed a bibliometric analysis of medical informatics citations indexed in medline using publication trends, journal frequencies, impact factors, Medical Subject Headings (MeSH) term frequencies, and characteristics of citations. Findings revealed that there were over 77,000 medical informatics articles published during the covered period in numerous journals and that the average annual growth rate was 12%. The MeSH term analysis also suggested a strong interdisciplinary trend. Finally, average impact scores increased over time with two notable growth periods. Overall, patterns in research outputs that seem to characterize the historic trends and current components of the field of medical informatics suggest it may be a maturing discipline (DeShazo et al., 2009).

9.3.3. Scoping Reviews

Scoping reviews attempt to provide an initial indication of the potential size and nature of the extant literature on an emergent topic (Arksey & O’Malley, 2005; Daudt, van Mossel, & Scott, 2013 ; Levac, Colquhoun, & O’Brien, 2010). A scoping review may be conducted to examine the extent, range and nature of research activities in a particular area, determine the value of undertaking a full systematic review (discussed next), or identify research gaps in the extant literature ( Paré et al., 2015 ). In line with their main objective, scoping reviews usually conclude with the presentation of a detailed research agenda for future works along with potential implications for both practice and research.

Unlike narrative and descriptive reviews, the whole point of scoping the field is to be as comprehensive as possible, including grey literature (Arksey & O’Malley, 2005). Inclusion and exclusion criteria must be established to help researchers eliminate studies that are not aligned with the research questions. It is also recommended that at least two independent coders review abstracts yielded from the search strategy and then the full articles for study selection ( Daudt et al., 2013 ). The synthesized evidence from content or thematic analysis is relatively easy to present in tabular form (Arksey & O’Malley, 2005; Thomas & Harden, 2008 ).

One of the most highly cited scoping reviews in the eHealth domain was published by Archer, Fevrier-Thomas, Lokker, McKibbon, and Straus (2011) . These authors reviewed the existing literature on personal health record ( phr ) systems including design, functionality, implementation, applications, outcomes, and benefits. Seven databases were searched from 1985 to March 2010. Several search terms relating to phr s were used during this process. Two authors independently screened titles and abstracts to determine inclusion status. A second screen of full-text articles, again by two independent members of the research team, ensured that the studies described phr s. All in all, 130 articles met the criteria and their data were extracted manually into a database. The authors concluded that although there is a large amount of survey, observational, cohort/panel, and anecdotal evidence of phr benefits and satisfaction for patients, more research is needed to evaluate the results of phr implementations. Their in-depth analysis of the literature signalled that there is little solid evidence from randomized controlled trials or other studies through the use of phr s. Hence, they suggested that more research is needed that addresses the current lack of understanding of optimal functionality and usability of these systems, and how they can play a beneficial role in supporting patient self-management ( Archer et al., 2011 ).

9.3.4. Forms of Aggregative Reviews

Healthcare providers, practitioners, and policy-makers are nowadays overwhelmed with large volumes of information, including research-based evidence from numerous clinical trials and evaluation studies, assessing the effectiveness of health information technologies and interventions ( Ammenwerth & de Keizer, 2004 ; Deshazo et al., 2009 ). It is unrealistic to expect that all these disparate actors will have the time, skills, and necessary resources to identify the available evidence in the area of their expertise and consider it when making decisions. Systematic reviews that involve the rigorous application of scientific strategies aimed at limiting subjectivity and bias (i.e., systematic and random errors) can respond to this challenge.

Systematic reviews attempt to aggregate, appraise, and synthesize in a single source all empirical evidence that meet a set of previously specified eligibility criteria in order to answer a clearly formulated and often narrow research question on a particular topic of interest to support evidence-based practice ( Liberati et al., 2009 ). They adhere closely to explicit scientific principles ( Liberati et al., 2009 ) and rigorous methodological guidelines (Higgins & Green, 2008) aimed at reducing random and systematic errors that can lead to deviations from the truth in results or inferences. The use of explicit methods allows systematic reviews to aggregate a large body of research evidence, assess whether effects or relationships are in the same direction and of the same general magnitude, explain possible inconsistencies between study results, and determine the strength of the overall evidence for every outcome of interest based on the quality of included studies and the general consistency among them ( Cook, Mulrow, & Haynes, 1997 ). The main procedures of a systematic review involve:

  • Formulating a review question and developing a search strategy based on explicit inclusion criteria for the identification of eligible studies (usually described in the context of a detailed review protocol).
  • Searching for eligible studies using multiple databases and information sources, including grey literature sources, without any language restrictions.
  • Selecting studies, extracting data, and assessing risk of bias in a duplicate manner using two independent reviewers to avoid random or systematic errors in the process.
  • Analyzing data using quantitative or qualitative methods.
  • Presenting results in summary of findings tables.
  • Interpreting results and drawing conclusions.

Many systematic reviews, but not all, use statistical methods to combine the results of independent studies into a single quantitative estimate or summary effect size. Known as meta-analyses , these reviews use specific data extraction and statistical techniques (e.g., network, frequentist, or Bayesian meta-analyses) to calculate from each study by outcome of interest an effect size along with a confidence interval that reflects the degree of uncertainty behind the point estimate of effect ( Borenstein, Hedges, Higgins, & Rothstein, 2009 ; Deeks, Higgins, & Altman, 2008 ). Subsequently, they use fixed or random-effects analysis models to combine the results of the included studies, assess statistical heterogeneity, and calculate a weighted average of the effect estimates from the different studies, taking into account their sample sizes. The summary effect size is a value that reflects the average magnitude of the intervention effect for a particular outcome of interest or, more generally, the strength of a relationship between two variables across all studies included in the systematic review. By statistically combining data from multiple studies, meta-analyses can create more precise and reliable estimates of intervention effects than those derived from individual studies alone, when these are examined independently as discrete sources of information.

The review by Gurol-Urganci, de Jongh, Vodopivec-Jamsek, Atun, and Car (2013) on the effects of mobile phone messaging reminders for attendance at healthcare appointments is an illustrative example of a high-quality systematic review with meta-analysis. Missed appointments are a major cause of inefficiency in healthcare delivery with substantial monetary costs to health systems. These authors sought to assess whether mobile phone-based appointment reminders delivered through Short Message Service ( sms ) or Multimedia Messaging Service ( mms ) are effective in improving rates of patient attendance and reducing overall costs. To this end, they conducted a comprehensive search on multiple databases using highly sensitive search strategies without language or publication-type restrictions to identify all rct s that are eligible for inclusion. In order to minimize the risk of omitting eligible studies not captured by the original search, they supplemented all electronic searches with manual screening of trial registers and references contained in the included studies. Study selection, data extraction, and risk of bias assessments were performed inde­­pen­dently by two coders using standardized methods to ensure consistency and to eliminate potential errors. Findings from eight rct s involving 6,615 participants were pooled into meta-analyses to calculate the magnitude of effects that mobile text message reminders have on the rate of attendance at healthcare appointments compared to no reminders and phone call reminders.

Meta-analyses are regarded as powerful tools for deriving meaningful conclusions. However, there are situations in which it is neither reasonable nor appropriate to pool studies together using meta-analytic methods simply because there is extensive clinical heterogeneity between the included studies or variation in measurement tools, comparisons, or outcomes of interest. In these cases, systematic reviews can use qualitative synthesis methods such as vote counting, content analysis, classification schemes and tabulations, as an alternative approach to narratively synthesize the results of the independent studies included in the review. This form of review is known as qualitative systematic review.

A rigorous example of one such review in the eHealth domain is presented by Mickan, Atherton, Roberts, Heneghan, and Tilson (2014) on the use of handheld computers by healthcare professionals and their impact on access to information and clinical decision-making. In line with the methodological guide­lines for systematic reviews, these authors: (a) developed and registered with prospero ( www.crd.york.ac.uk/ prospero / ) an a priori review protocol; (b) conducted comprehensive searches for eligible studies using multiple databases and other supplementary strategies (e.g., forward searches); and (c) subsequently carried out study selection, data extraction, and risk of bias assessments in a duplicate manner to eliminate potential errors in the review process. Heterogeneity between the included studies in terms of reported outcomes and measures precluded the use of meta-analytic methods. To this end, the authors resorted to using narrative analysis and synthesis to describe the effectiveness of handheld computers on accessing information for clinical knowledge, adherence to safety and clinical quality guidelines, and diagnostic decision-making.

In recent years, the number of systematic reviews in the field of health informatics has increased considerably. Systematic reviews with discordant findings can cause great confusion and make it difficult for decision-makers to interpret the review-level evidence ( Moher, 2013 ). Therefore, there is a growing need for appraisal and synthesis of prior systematic reviews to ensure that decision-making is constantly informed by the best available accumulated evidence. Umbrella reviews , also known as overviews of systematic reviews, are tertiary types of evidence synthesis that aim to accomplish this; that is, they aim to compare and contrast findings from multiple systematic reviews and meta-analyses ( Becker & Oxman, 2008 ). Umbrella reviews generally adhere to the same principles and rigorous methodological guidelines used in systematic reviews. However, the unit of analysis in umbrella reviews is the systematic review rather than the primary study ( Becker & Oxman, 2008 ). Unlike systematic reviews that have a narrow focus of inquiry, umbrella reviews focus on broader research topics for which there are several potential interventions ( Smith, Devane, Begley, & Clarke, 2011 ). A recent umbrella review on the effects of home telemonitoring interventions for patients with heart failure critically appraised, compared, and synthesized evidence from 15 systematic reviews to investigate which types of home telemonitoring technologies and forms of interventions are more effective in reducing mortality and hospital admissions ( Kitsiou, Paré, & Jaana, 2015 ).

9.3.5. Realist Reviews

Realist reviews are theory-driven interpretative reviews developed to inform, enhance, or supplement conventional systematic reviews by making sense of heterogeneous evidence about complex interventions applied in diverse contexts in a way that informs policy decision-making ( Greenhalgh, Wong, Westhorp, & Pawson, 2011 ). They originated from criticisms of positivist systematic reviews which centre on their “simplistic” underlying assumptions ( Oates, 2011 ). As explained above, systematic reviews seek to identify causation. Such logic is appropriate for fields like medicine and education where findings of randomized controlled trials can be aggregated to see whether a new treatment or intervention does improve outcomes. However, many argue that it is not possible to establish such direct causal links between interventions and outcomes in fields such as social policy, management, and information systems where for any intervention there is unlikely to be a regular or consistent outcome ( Oates, 2011 ; Pawson, 2006 ; Rousseau, Manning, & Denyer, 2008 ).

To circumvent these limitations, Pawson, Greenhalgh, Harvey, and Walshe (2005) have proposed a new approach for synthesizing knowledge that seeks to unpack the mechanism of how “complex interventions” work in particular contexts. The basic research question — what works? — which is usually associated with systematic reviews changes to: what is it about this intervention that works, for whom, in what circumstances, in what respects and why? Realist reviews have no particular preference for either quantitative or qualitative evidence. As a theory-building approach, a realist review usually starts by articulating likely underlying mechanisms and then scrutinizes available evidence to find out whether and where these mechanisms are applicable ( Shepperd et al., 2009 ). Primary studies found in the extant literature are viewed as case studies which can test and modify the initial theories ( Rousseau et al., 2008 ).

The main objective pursued in the realist review conducted by Otte-Trojel, de Bont, Rundall, and van de Klundert (2014) was to examine how patient portals contribute to health service delivery and patient outcomes. The specific goals were to investigate how outcomes are produced and, most importantly, how variations in outcomes can be explained. The research team started with an exploratory review of background documents and research studies to identify ways in which patient portals may contribute to health service delivery and patient outcomes. The authors identified six main ways which represent “educated guesses” to be tested against the data in the evaluation studies. These studies were identified through a formal and systematic search in four databases between 2003 and 2013. Two members of the research team selected the articles using a pre-established list of inclusion and exclusion criteria and following a two-step procedure. The authors then extracted data from the selected articles and created several tables, one for each outcome category. They organized information to bring forward those mechanisms where patient portals contribute to outcomes and the variation in outcomes across different contexts.

9.3.6. Critical Reviews

Lastly, critical reviews aim to provide a critical evaluation and interpretive analysis of existing literature on a particular topic of interest to reveal strengths, weaknesses, contradictions, controversies, inconsistencies, and/or other important issues with respect to theories, hypotheses, research methods or results ( Baumeister & Leary, 1997 ; Kirkevold, 1997 ). Unlike other review types, critical reviews attempt to take a reflective account of the research that has been done in a particular area of interest, and assess its credibility by using appraisal instruments or critical interpretive methods. In this way, critical reviews attempt to constructively inform other scholars about the weaknesses of prior research and strengthen knowledge development by giving focus and direction to studies for further improvement ( Kirkevold, 1997 ).

Kitsiou, Paré, and Jaana (2013) provide an example of a critical review that assessed the methodological quality of prior systematic reviews of home telemonitoring studies for chronic patients. The authors conducted a comprehensive search on multiple databases to identify eligible reviews and subsequently used a validated instrument to conduct an in-depth quality appraisal. Results indicate that the majority of systematic reviews in this particular area suffer from important methodological flaws and biases that impair their internal validity and limit their usefulness for clinical and decision-making purposes. To this end, they provide a number of recommendations to strengthen knowledge development towards improving the design and execution of future reviews on home telemonitoring.

9.4. Summary

Table 9.1 outlines the main types of literature reviews that were described in the previous sub-sections and summarizes the main characteristics that distinguish one review type from another. It also includes key references to methodological guidelines and useful sources that can be used by eHealth scholars and researchers for planning and developing reviews.

Table 9.1. Typology of Literature Reviews (adapted from Paré et al., 2015).

Typology of Literature Reviews (adapted from Paré et al., 2015).

As shown in Table 9.1 , each review type addresses different kinds of research questions or objectives, which subsequently define and dictate the methods and approaches that need to be used to achieve the overarching goal(s) of the review. For example, in the case of narrative reviews, there is greater flexibility in searching and synthesizing articles ( Green et al., 2006 ). Researchers are often relatively free to use a diversity of approaches to search, identify, and select relevant scientific articles, describe their operational characteristics, present how the individual studies fit together, and formulate conclusions. On the other hand, systematic reviews are characterized by their high level of systematicity, rigour, and use of explicit methods, based on an “a priori” review plan that aims to minimize bias in the analysis and synthesis process (Higgins & Green, 2008). Some reviews are exploratory in nature (e.g., scoping/mapping reviews), whereas others may be conducted to discover patterns (e.g., descriptive reviews) or involve a synthesis approach that may include the critical analysis of prior research ( Paré et al., 2015 ). Hence, in order to select the most appropriate type of review, it is critical to know before embarking on a review project, why the research synthesis is conducted and what type of methods are best aligned with the pursued goals.

9.5. Concluding Remarks

In light of the increased use of evidence-based practice and research generating stronger evidence ( Grady et al., 2011 ; Lyden et al., 2013 ), review articles have become essential tools for summarizing, synthesizing, integrating or critically appraising prior knowledge in the eHealth field. As mentioned earlier, when rigorously conducted review articles represent powerful information sources for eHealth scholars and practitioners looking for state-of-the-art evidence. The typology of literature reviews we used herein will allow eHealth researchers, graduate students and practitioners to gain a better understanding of the similarities and differences between review types.

We must stress that this classification scheme does not privilege any specific type of review as being of higher quality than another ( Paré et al., 2015 ). As explained above, each type of review has its own strengths and limitations. Having said that, we realize that the methodological rigour of any review — be it qualitative, quantitative or mixed — is a critical aspect that should be considered seriously by prospective authors. In the present context, the notion of rigour refers to the reliability and validity of the review process described in section 9.2. For one thing, reliability is related to the reproducibility of the review process and steps, which is facilitated by a comprehensive documentation of the literature search process, extraction, coding and analysis performed in the review. Whether the search is comprehensive or not, whether it involves a methodical approach for data extraction and synthesis or not, it is important that the review documents in an explicit and transparent manner the steps and approach that were used in the process of its development. Next, validity characterizes the degree to which the review process was conducted appropriately. It goes beyond documentation and reflects decisions related to the selection of the sources, the search terms used, the period of time covered, the articles selected in the search, and the application of backward and forward searches ( vom Brocke et al., 2009 ). In short, the rigour of any review article is reflected by the explicitness of its methods (i.e., transparency) and the soundness of the approach used. We refer those interested in the concepts of rigour and quality to the work of Templier and Paré (2015) which offers a detailed set of methodological guidelines for conducting and evaluating various types of review articles.

To conclude, our main objective in this chapter was to demystify the various types of literature reviews that are central to the continuous development of the eHealth field. It is our hope that our descriptive account will serve as a valuable source for those conducting, evaluating or using reviews in this important and growing domain.

About Literature Tables and Writing a Synthesis

A literature table is a way to organize the articles you've selected for inclusion in your publication. There are many different types of literature tables-the main thing is to determine the important pieces that help draw out the comparisons and contrasts between the articles included in your review. The first few columns should include the basic info about the article (title, authors, journal), publication year, and the purpose of the paper.

While the table is a step to help you organize the articles you've selected for your research, the literature synthesis can take many forms and can have multiple parts. This largely depends on what type of review you've undertaken. Look back at the examples under Literature and Other Types of Reviews to see examples of different types of reviews.
